I'm going to guess that

you're suppose to put how many electrons are on each shell by the atomic number of the element.

for example: Oxygen is represented by O on the periodic table. Its atomic number is 8. So there would be 2 electrons in each of the 4 shells because 2 * 4 = 8 ( the atomic number)

A 50 L cylinder is filled with argon gas to a pressure of 10130.0 kPa at 300°C. How many moles of argon gas does the cylinder co

Vlad1618 [11]

To answer this question, we will use the general gas law which states that:
PV = nRT where:
P is the pressure of the gas = 10130.0 kPa
V is the volume of the gas = 50 liters
n is the number of moles that we want to calculate
R is the gas constant = 8.314 L∙kPa/K∙mol
T is the temperature = 300+273 = 573 degree kelvin

Substitute with the givens in the equation to get the number of moles as follows:
10130 * 50 = n * 8.314 * 573
506500 = 4763.922 n
n = 506500 / 4763.922
n = 106.3199 moles
